Title: Spring mount for label applicator tamp pad
Inventor: BIXEN ROBERT W
IPC: B65C9/18
Filed: 2003-12-11
Abstract: A swivel mount is configured for use with a tamp pad for a label applicator of the type for receiving a label at a first retracted position and applying the label to an object at a second, extended position. The mount includes a mounting block for fastening to the tamp pad. The mounting block has a bore therein having an inner, open cross-sectional region and a retaining region. A knuckle fitting is received within the bore and is engageable with the retaining region. The knuckle fitting has a largest cross-sectional area that is larger than the open cross-sectional area of the retaining region such that a portion of the knuckle fitting is retained within the bore.  A spring is positioned to provide a force against the knuckle fitting against the retaining region. The mount permits movement of the tamp pad from an orientation perpendicular to a direction of movement between the retracted and extended positions to an orientation inclined relative to the direction of movement.

Title: Continuous magnetic field gradient separation
Inventor: BOSE ARIJIT
IPC: B03C1/01
Filed: 2002-08-20
Abstract: A continuous, hybrid magnetic field gradient device for colloidal magnetic affinity separation having an axially-rotating horizontal glass tube, and a plurality of axially located repeating magnetic units. Each magnetic units consists of an alternating current solenoid that surrounds the chamber followed by computer-controlled electromagnets carrying a direct current. Th e on-off cycle of the electromagnets is used to control the residence time of target-bound magnetic particles in the chamber thereby allowing the separate collection of the particle and target rich fractions and the target-lean fractions without interrupting the feed flow. The azimuthally flowing alternating current in the solenoid introduces transient axial and radial forces as well as torque on the magnetic particles, promoting mixing.</SDOAB >

Abstract: A method and apparatus for centering a log allow a optimum yield axis and a maximum radius of rotation of the log to be calculated more accurately than conventionally possible. The angle of rotation of a log M is detected by a rotation angle detector 6 that is engaged with a preliminary axis c about which the log M is rotated. A contour of the log for calculating the optimum yield axis of the log and a contour for calculating the maximum radius of rotation of the log are measured separately. The contour for calculating the optimum yield axis is measured in a fixed-point manner by measuring the log at a plurality of certain measurement points with beam reflection scanners 8 disposed at appropriate intervals along the axis of the log M. The contour for calculating the maximum radius of rotation is measured in a comprehensive manner by measuring the log in a plurality of measurement sections allocated on the log along the axis thereof with virtually no gap therebetween, using swing-angle detectors 15 engaged with contact-swinging detection members provided individually in the plural measurement sections.

IPC: A61B19/00
Filed: 2003-02-28
Abstract: A computer based system (200) generating audible feedback (260) to assist with guidance of at least one trackable point in space is provided. Surgical embodiments include generating audible feedback (260) (to supplement visual and tactile feedback) to a surgeon moving the tip (235) of a probe (230), for example, in a surgical field with respect to a volume of interest such as a tumor (100). Other surgical embodiments include generating audible feedback (260) to assist with the precise insertion of a pedicle screw. In such surgical embodiments, as a surgeon moves a probe or instrument (230) within the surgical field, a computer (200) analyzes the current position of the probe and/or instrument (230) in space with respect to a system of fiducial markers (240, 242, 244, and 246). The computer (200) then provides audible feedback (260) to the surgeon as to the position of the probe and/or instrument (230) with respect to predetermined feature(s) of interest (such as a tumor (100)) previously identified on a computer reconstruction of the surgical view obtained, for example, by a magnetic resonance imaging (MRI) scan, a computerized tomography (CT) scan and/or an ultrasound scan. The audible feedback (260) may vary in numerous ways, such as in tone, volume, pattern and/or style, as the probe and/or instrument (230) moves relative to the feature(s) of interest.

Title: Faraday flashlight
Inventor: MAH PAT Y
IPC: H02K35/02
Filed: 2003-03-24
Abstract: A light generating flashlight system device utilizes a large centrally locat ed magnet which is mounted to slide past a magnet pickup or current induction wire which may be preferably mounted at a center point of travel in a tubula r housing having a tubular chamber through which the magnet travels. A pair of elastomeric dampers are located each at the end of a support system sleeve which is sized to fit within a main housing to stabilize all internal suppor t within a sealed unit. The result is a device which facilitates the manual movement of the flashlight body, and also conserves the residual momentum of the magnet once it has traveled past the magnet pickup or current induction wire by providing a bumper and spring to conserve some of the mechanical energy going in the other direction. A ready charger is disclosed which uses induction to charge the flashlight system by proximity to the manual chargin g magnet wire.
